<h1>RGraph: <span>Javascript charts library</span> - Radar charts</h1>

    <div style="background-color: #ffb; border: 2px dashed #000; padding: 3px">
        This chart used to be called the Tradar chart (T standing for "Traditional" - there used to be two Radar charts in RGraph),
        however now (July 2011), it has been renamed to the "Radar" chart to make it easier for people to identify. If you use it
        you will need to update your code accordingly. Keep in mind that if you use the .type property - this has been updated too
        (to <i>radar</i>).
    </div>
 
    <script>
        if (RGraph.isIE8()) {
            document.write('<div style="background-color: #fee; border: 2px dashed red; padding: 5px"><b>Important</b><br /><br /> Internet Explorer 8 does not natively support the HTML5 canvas tag, so if you want to see the charts, you can either:<ul><li>Install <a href="http://code.google.com/chrome/chromeframe/">Google Chrome Frame</a></li><li>Use ExCanvas. This is provided in the RGraph Archive.</li><li>Use another browser entirely. Your choices are Firefox 3.5+, Chrome 2+, Safari 4+ or Opera 10.5+. </li></ul> <b>Note:</b> Internet Explorer 9 fully supports the canvas tag.</div>');

        Radar charts, that are similar to Rose charts. Each of the data points is
        arranged equally in terms of angle, whilst the magnitude of each point is shown by the distance from the centre. Thus,
        data points of a higher magnitude can be seen as they are more distant from the centre.
    </p>
    
    <p>
        Suitable for many datasets, but not all. If not, then Rose charts may be more apt.
    </p>
    
    <p>
        The circle, as can be seen in the second example, could be used to indicate a threshold of sorts. In the example,
        it could be minimum sales required for a particular month. Months that fall below this threshold can be clearly seen.
